▎ 摘　　要

Graphene is a two-dimensional nanomaterial that has unique electrical, mechanical, thermal, and optical properties. For realizing the practical applications of graphene, one of the major challenges lies in cost-effective production of graphene-based nanomaterials at a large scale. Significant research efforts have been demonstrated in regard to scalable manufacturing of graphene and show strong potential for their commercialization and industrialization. Here, we review the state-of-the-art techniques developed for the scalable production of graphene. This review mainly discusses the top-down techniques including exfoliation of bulk graphite and chemical reduction of graphene oxide. Critical comparison for graphene quality, structure, and yields for different techniques is discussed and specific examples are described in detail.
